Who's feast day is today on the Christian calendar?

I don't have a devotion to St. John Chrysostom, but I did go to M today and Fr. Jerry had a nice talk about him. I learned the he was very strong in preaching and writing to explained Catholic doctrine and presented the ideal Christian life. For this reason, he is call Chrysostom or Golden Mouth. Therefore, don't think of the word "chrysostom" as his last name, which I'm sure people sometime do.
